Sox make Napoli signing official

The Red Sox made the signing of Mike Napoli official Tuesday, sending out an announcement from general manager Ben Cherington. To make room for Napoli on the 40-man roster, right-handed pitcher Chris Carpenter (who was compensation from the Cubs for Theo Epstein) was designated for assignment.

Napoli is scheduled to be on a call with reporters at 4:30 p.m. ET, so we'll have more after that.
